µTomo beamline
X-ray microtomography setup
Innovative aspects:
•
Phase contrast images are obtained by using the X-ray beam
•
Chemically resolved radiography for an efficient quantitative analysis by means
of the X-ray tunability
•
Hard X-ray are used for high Z elements mapping
Experimental techniques:
•
PHase Contrast (PHC) radiography
•
Chemically resolved radiographic images
•
Micro-tomography and holotomography
